' Specification of Lettersggatenta' To all whom it may concern: I

Be it known thatwe-{Fng NK HERRMANN and O'r'ro H. A. H-ERRM NN, citizensof the United States, residing at Brooklyn, in the county of Kings,State of New York, have .invented certain new and useful Improve- Thisinvention relates to gas stoves and has special reference to portablegas stoves adapted for use in connection with the ordinary gas jet orburner.

One important object of the invention is to provide an improved andsimplified unitary structure which may be cast in one piece and whichwill be economical to manufacture and of such characteras to bepractically impossible to get out of order.

A. second important object of the invention is to provide means forproperly distributing the gas so as to produce an even heating of anarticle placed on the stove.

A third important object of the invention is to provide an improvedstructure having a peculiar form of flame guard in comiection therewith.

With the above and other objects in view,

' as will be hereinafter apparent the invention consists in general ofcertain novel details of construction and combinations of partshereinafter fully described, illustrated in the accompanying drawing,and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

-Figure 1 is a perspective view showing the device in use on a gasstove.

Fig. 2 is a plan view of the device.

Fig. 3 is a side elevation of the device.

Fig.- 4: is a vertical median section through the device.

In carrying out the objects of the present invention there is provided abody portion the lower part of which forms a1bowlshaped structure 10while the upper part formsa similar bowl shaped structure 11, the upperbowl being of greater diameter and relatively flatter than the lowerbowl 10. The bottom 12 of the upper bowl 11 is downwardly curved so thatthe bottom 1s convexed so that at the same time th1s bottom 12 forms:the top. of the bowl 10, the top...

being thus concaved. rm, ectingdown. from the center of the, bottom of 7the bowl '10 is.

a tube13 which is adapted to fit on the usual that there will be noescape of gas between the burner and the tube 13. Drilled around theperiphery of the bottom 12 is a series of holes 14 from which the gascontained in the receptacle formed by the bowl 10 escapes. It will benoted that by the downward curvature or bulging of the bottom 12 the gaswhich flows in through the neck 13 is spread laterally so that it passesevenly out of the holes or openings 14, thus en'- abling it to belighted at these points and produce an even ring flame.

The upper edge of the bowl 11 is flanged outwardly as at 15 and alsoflanged inwardly as at 16, the flanges forming continuations of eachother.

By reason of the flange 16 the flame which is spread by the pan or otherarticle set on the stove will not pass out around the edges of the panbut will be deflected by the flange 16.

' In order to provide for theescape of the products of combustion thereis employed a plurality of openings 17 formed in the side We... l i

r mmed case; 1,9152;

gas burner, the fit being tightenough so wall of the bowl 11, theseopenings being preferably three in number although other numbers may beused if desired without affecting the principle of the invention.

From the foregoing construction it will be seen that the entire devicemay be readily cast of thin metal, cores being employed in the bowls 10and 11, the only machinery necessary being the drilling of the holes 14:and reaming out of the neck '13 to the proper fit, although it may bedesirable to face ofl' the flanges 15 and 16.

'There has thus been provided a simple and efiicient device of the kinddescribed and for the purpose specified.

It is'obvious that many. minor changes may be made in the form andconstruction of the invention without departing from prop- I and anupper bowl like portion, the upper portion being wider and relativelyshallower than the lower portion, the bottom of the. upper portion beingdownwardly bulged and forming the top of the lower bowl said bottombeing provided with an annular series of gas escape openings adjacentits periphery, the upper bowl having a peripheral series of openingsadjacent its edge for the escape of the products of combustion, aninwardly extending flame deflecting flange on the edge of theupper bowland a centrally disposed depending neck formed centrally of the lowerbowl and arranged to 15 fit a gas jet or burner.

In testimony whereof, we aifix our signatures in the presence of twowitnesses.
